We have a particular affinity for vintage Ampeg gear here at RR, and the collection currently includes three different eras of B15 PortaFlex amps (early 60s, late 60s, and 70s), a 60s Gemini, and a 60s B-12X. The B12X is a pretty unique beast, with a fantastic tremolo and a small satellite "echo" (reverb) speaker that can be mic'ed separately for tons of sonic fun.
